But T-Mobile USA has yet to bring the iPhone to their network in any official capacity, in part because their 3G network uses a different radio frequency band than AT&T and the rest of the world, one that current iPhone hardware does not support.

Unlocked iPhone owners will be quite familiar with this limitation, as unlocked devices built for AT&T’s network will fall back to 2G EDGE service when used with a T-Mobile USA sim card. Read more

As 9to5Mac’s Mark Gurman explains, the numbering in this particular section of code in iOS 5.1 suggests that Apple will be shipping a quad core processor at some point in the near future:

Extremely reliable and knowledgeable people familiar with iOS’s inner workings explained to me that core references begin at “0.” For example: A single core device would be limited to ”/cores/core.0,” and a dual-core device would come in at ”/cores/core.1.” A “core.2″ (which is not referenced in iOS code) would be a triple-core processor according to this labeling method. iOS 5.1 beta 2 now includes core.3, a seemingly quad-core chip from Apple.

Apple’s A6 is rumored to be a quad core design slated for release in 2012, might we be seeing the initial support in iOS necessary for an A6-bearing iPad 3? Read more

Several of our followers on Twitter and Facebook have recently expressed interest in the state of Apple’s efforts to merge its various forms of messaging/chat/videoconferencing/IM functionality across its two key platforms, iOS and Mac OS X. New code spotted in iOS by third party developers may shed some light on this. Read more

The next-generation iPhone and iPod Touch will be based on a unique type of OLED display, according to sources, which is far more shatter-resistant than the current “gorilla glass” and LCD design used in the iPhone 4/4S and previous generations.

One of the chief problems with the iPhone and iPod Touch to date has been its easily damaged glass touch screen, and in the case of the iPhone 4/4S, the glass back panel. The iPhone 5 and its corresponding iPod Touch cousin will, according to a report just in from sources familiar with Apple’s 2012 Hardware Roadmap, replace the “square” design of the iPhone 4 and 4S with a solid frame — in some prototypes, this is metal (usually aluminum, though Titanium has been explored due to its superior strength in extremely thin configurations) and in others, a thermoplastic carbon fiber material — and a new type of capacitative touchscreen which incorporates a much tougher, nearly shatterproof outer surface material with an organic LED (OLED) display that is significantly larger than today’s “retina” TFT LCD.

This morning, Apple sent out press invites to an event scheduled for 10am Pacific time October 4th (next tuesday) on Apple’s campus in Cupertino.

As Steve Jobs is no longer the CEO of Apple, Tim Cook will lead the presentation while other Apple executives may take smaller roles on stage periodically.

For the past few years, Apple has used their annual WWDC event during the summer to announce a new iPhone model and to release the next version of iOS. Neither of those things happened this past WWDC, but iOS 5 is currently at the very end of beta testing so a release next tuesday would line up perfectly.

Apple is also rumored to be planning to release a new iPhone 5 model, containing the same A5 processor and improved graphics capabilities that debuted in the iPad 2 earlier this year, as well as a lower cost iPhone ‘4s’ model. Read more

Apple has announced the time and place for their World Wide Developers Conference this year. It will be held at the Moscone Center in San Francisco June 6th through June 10th.

Over 1,000 Apple engineers guide you through five exciting days of in-depth technical sessions and hands-on labs that demonstrate how to harness the incredible power of the world’s most advanced operating systems into your apps.

Apple currently lists 5 “technology tracks” that will be the theme of developer labs and sessions –

Application Frameworks

Graphics, Media, and Games

Developer Tools

Internet and Web

Core OS

In addition, Apple will once again be hosting the Apple Design Awards which “recognize technical excellence and outstanding achievement in iPhone, iPad, and Mac app design and development”. Read more

Apple has posted 4 similar job opportunities over at jobs.apple.com with the following 3 things listed as “Valuable knowledge” that would be helpful for the position:

Deep knowledge of Computational Geometry or Graph Theory

Experience with Linux server-side development of distributed systems

Experience developing navigation software (emphasis ours)

The job title is listed as “iOS Software Engineer”, and the pitch for the job includes the phrase “build the world’s best hosted platforms at massive scale”.

Given the job description, it’s likely that Apple is planning to add navigation functionality to the iOS Maps application, or perhaps release a new Navigation App which would offer live turn by turn directions read aloud, along with the “point of view” 3D map that GPS owners are accustomed to.
